IMPROVEMENT IN BALING-PRESSES The Schedule referred to in these Letters Patent and making peut of the same.

To all whom it may concern Be it known that I, HENRY H. TIFT, of Mystic, in the county of `New London, and State of Connnecticut, have invented a new and useful Improvement in Billing-Presses, and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact spccitication of the saine, .wherein I have set forth the nature and principles of my said improvement, by which my invention may be'distinguished from all others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

This invention relates to a new and useful improve*- ment in that class of baling-presses in which toggles or toggle-levers are employed for operating the platens.

The object of the invent-ion is to render this class of presses (those built on the upright plan) far more durableI and stronger than they now are, and this is effected by having the rightand left-hand screw, by which the togglcs are operated, firmly supported, in such a manner that it cannot be deflected or bent out of a right line, and without causing any undue friction in the operation of the press.

The upright billing-presses of this class are provided, of course, with a horizontal screw, which is very liable to become bent or deflected from a right line, nn'der the weight ofthe bale or article being pressed.

My inventiqn fully obviatesthis ditticulty, as will be clearly seen from the following description.

In the accompanying sheet ofdrawings- Figure l is a sectional elevation of my invention, taken in the line x x, iig. 2.`

Figure 2, ahorizontal section of the same, taken in the line y y, tig. l.

Similar letters of reference indicate vcorresponding parts in the several drawings.

A represents the framing of the press, which may be constructed in any propel' manner to insure strength and durability.

B represents the press-box, in which two platens O O' work up and down simultaneously toward and from each other. s

The u per platen Gis attached to rods a, four in number, one at each angle or corner of the platen, and these rods extend downward, and are attached at their lower ends to a sliding plate, D, to which the lower ends of toggles Elare connected by pivots b,

the upper ends of said toggles being connected by pivots b' to nuts F F, through which a right and lefthand screw, Gr, passes, the right-hand thread passing or working through one nut, and the left-hand thread passingthrough the other.

The other platen G is tted, and allowed to work loosely upon the rods a, as guides, and this platen C has pivoted te its under side the upper ends of toggles H, the lower ends of the latter being pivoted to the nuts F F.

lhe nuts F F have trunnions, or bearings c projecting out from them, one from each sidc,.and these trunnions, or bearings rest and work upon horizontal guides I, firmly secured to the framing A.

From the above description, it will be seen that the screw G will be effectually sustained in position while being turned, and tbe platens C C moved toward and from cach other, under the action of the toggles E H.

The screw G. is relieved of the weight of the bale between the platens C C' by the trunnions, or bearings' c, which rest or bear upon the guides I, and are allowed to slide freely thereon.

It will be understood, of course, that the screw G is not liable to be bent or deflected out of a right line under the action of the toggles, as the pressure of one pair of toggles is counter-poised by that of the other.

The weight of .the bale is what would bend or dedect the screw, if the latter were not supported by the trunnions, or bearings c, resting on the guides I.

I wisl; it to be distinctly understood that I lay no claim to the toggles, and the right and left-hand screw and nuts, for operating the platens of haliug-presses, for these parts have been p revionsly used for such purpose; but

I do claini as new, and desire to secure by Letters Patent- In an upright toggle-lever billing-press, the trunnions, or bearings c, projecting from the nuts F l of the right and left-hand screw G, in combination with the guides I, on which the trunnions, or bearings c rest, all being arranged to operate in the manner substantially as and for the purpose set forth.

HENRY H. TIFT.
